i have gone through its data sheet. the slew rate of suggested op-amp LM741 is 5 V/microsecond that is much higher than slew rate of LMC6041 i.e. 0.015 V/microsecond. please refer some other op-amp meeting requirement of LMC6041 op-amp slew rate......
i m not finding LMC6041 at any Electronics shop at Karachi....

The LMC6041 opamp our OP is talking about is rail-to-rail input and output, is a micropower opamp with extremely low current supply requirements, and it's input current requirement is extremely small. I wouldn't be worried about having a higher slew rate; it's the R-R I/O and extremely high input impedance that I would be looking for. If he's trying to repair an existing device, he'll need an opamp with similar characteristics and pinout.
